RELATED APPLICATIONS

This application claims priority under 35 U.S.C. §119 from United Kingdom Patent Application No. 1314619.6, filed on Aug. 15, 2013, which is incorporated by reference in its entirety.

FIELD OF INVENTION

The inventive subject matter relates to the field of computer system monitoring. In particular, the invention relates to computer system productivity monitoring.

BACKGROUND OF INVENTION

In the vast majority of office environments, employees are allocated a computer to use as a workstation. This workstation is typically used for a period of 3-5 years, and then refreshed due to a number of factors such as:

1. Depreciation of the workstation. Computers typically depreciate their total value over a period of three years, meaning that a refresh cycle is usually no shorter than three years. 2. Advances in technology leading to cost savings. Newer technology may be introduced which can offer the company cost savings over currently deployed systems, with features such as enhanced power efficiency. 3. Lack of support for older systems. Old hardware and software typically requires increased support costs over time. This can be a driver for the replacement of older systems with new systems that are cheaper to support. 4. Damage to the workstation. As a workstation is used, the condition degrades over time. This can eventually make the machine likely to fail, or no longer fit for purpose.

Points 1, 2 and 3 are typically mitigated by companies by employing a strategy of issuing a hardware refresh every set number of years, typically between 3 and 5. The length of time may be manually altered based on strategic choices; for example, if a particular operating system is going out of support soon, the hardware refresh might be accelerated to take this into account.

Point 4 is much more difficult to mitigate using a broad stroke approach. It is difficult for an organization to quantify the effect of wear and tear, and put definite metrics against loss of productivity due to the machine being less fit for purpose.

A typical example of the user losing productivity due to an old workstation would be if the workstation were no longer quick enough to run the most recent version of the standard email client in a satisfactory manner. The email program could take two minutes to load in the morning instead of 30 seconds. This would likely result in the worker going for a five minute coffee break, which results in that time being lost on a regular basis.

A hardware refresh can be costly to a business. It is not only the cost of the new workstations, but the cost of disposal of the old workstations, loss of productivity during workstation migration, and environmental impact if the refresh is carried out more often than necessary

DESCRIPTION OF EMBODIMENT(S)

It will be appreciated that for simplicity and clarity of illustration, elements shown in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity. Further, where considered appropriate, reference numbers may be repeated among the figures to indicate corresponding or analogous features.

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the inventive subject matter. However, it will be understood by those skilled in the art that the inventive subject matter may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the inventive subject matter.

Methods and systems are provided for monitoring aspects of a computer system including hardware sensor data to build a profile of the usage of the workstation. The profile may be used to assess whether the performance of the workstation is an inhibitor to productivity, and thus whether an upgraded workstation would be justified by the resultant productivity gains, or alternatively, if the workstation's performance is satisfactory for its current usage.

The analysis may be carried out in or around the standard refresh window for the computer system. That is, if standard policy is to refresh a computer system at 4 years, this analysis should be in place, for example, for a period of 2-6 years from the last refresh.

Over time, performance and suitability for use of a workstation declines. For certain uses, that decline becomes significant earlier, while for other uses, the decline has less of an impact. It would be advantageous to have a means for tying these factors together to achieve maximum useful life from a workstation.

A method is described of combining various metrics with logs showing the types of activity the system is used for. These factors, taken together, give a better image of when the useful life of the machine is coming to an end. The factors may be combined using weighting factors to flag up the approach to end of useful life. The factors may be combined as a weighted function of usage of the machine.

Referring to FIG. 1, a block diagram shows an example embodiment of the described system 100.

A computer system 110 is shown which is to be monitored. Multiple computer systems may be monitored simultaneously, particularly across multiple computer systems of an enterprise.

The computer system 110 to be monitored may be a desktop computer, a laptop computer, a tablet computer, a smart phone, a server computer, etc. The computer system 110 may have multiple sensors 111-113 for collecting data relating to the performance of the computer system 110. Further details of an example computer system having multiple sensors is shown in FIG. 2.

A productivity monitoring component 120 is provided which may include a data collection component 121 for collecting data from the sensors 111 of the computer system. The productivity monitoring component 120 may include a performance profile component 122 for generating a profile of resource performance and other monitored metrics of the computer system 110, and a usage profile component 123 for generating a profile of the current activities and use of the computer system 110.

An analysis component 124 may be provided for comparing the performance profile and the usage profile (i.e., the profile of performance of the computer system is analyzed against the profile of usage of the computer system). The analysis component 124 may include a weighting component 126 for providing a weighting function based on the usage profile generated by the usage profile component 123. The analysis component 124 may assess the performance profile and usage profile components together; for example, if one resource is under performing, then this may be correlated to the usage of another resource, which builds the case for a system upgrade.

A decision component 124 may be provided for determining whether a computer system 110 should be transferred to another use or discontinued and the system upgraded

Referring to FIG. 3, an exemplary system for implementing aspects of the inventive subject matter such as the productivity monitoring component includes a data processing system 300 suitable for storing and/or executing program code including at least one processor 301 coupled directly or indirectly to memory elements through a bus system 303. The memory elements may include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution.

The memory elements may include system memory 302 in the form of read only memory (ROM) 304 and random access memory (RAM) 305. A basic input/output system (BIOS) 306 may be stored in ROM 304. System software 307 may be stored in RAM 305 including operating system software 308. Software applications 310 may also be stored in RAM 305.

The system 300 may also include a primary storage means 311 such as a magnetic hard disk drive and secondary storage means 312 such as a magnetic disc drive and an optical disc drive. The drives and their associated computer-readable media provide non-volatile storage of computer-executable instructions, data structures, program modules and other data for the system 300. Software applications may be stored on the primary and secondary storage means 311, 312 as well as the system memory 302.

The computing system 300 may operate in a networked environment using logical connections to one or more remote computers via a network adapter 316.

Input/output devices 313 may be coupled to the system either directly or through intervening I/O controllers. A user may enter commands and information into the system 300 through input devices such as a keyboard, pointing device, or other input devices (for example, microphone, joy stick, game pad, satellite dish, scanner, or the like). Output devices may include speakers, printers, etc. A display device 314 is also connected to system bus 303 via an interface, such as video adapter 315.

Referring to FIG. 4, a flow diagram 400 shows an example embodiment of the described method.

The method may start monitoring 401 a computer system which may be one of multiple computer systems being monitored simultaneously. The monitoring may be carried out within a given time period of a scheduled refresh of hardware and/or software.

Data may be gathered 402 from multiple sensors provided in the computer system. This data may be gathered over a set period of time or continuously. The data may be gathered from sensors as described in relation to FIG. 3 above.

A profile may be generated 403 of the performance of the computer system including resource performance such as the CPU usage, disk drive access frequency, and latency, speed of running applications, and other metrics, such as temperature, battery lifetime, etc.

Resource monitoring for the generation of a performance profile may be the lowest level of monitoring available for a resource. For example:

-   -   Fan spin speeds as a percentage of rated maximum;     -   Battery charge level after 10 minutes of charging;     -   Hard disk drive sequential read throughput;     -   Hard disk drive average seek time for random block read and         write;     -   Hard disk drive platter vibration levels.

A profile may be generated 404 of the usage of the computer system including applications being run, accelerometer data regarding the physical handling of the computer system, battery/power usage, temperature of surroundings, etc.

Usage monitoring for generating a usage profile may be a higher level of profiling, usually from the Operating System point of view, including:

-   -   CPU usage;     -   Hard disk drive usage;     -   System temperature;     -   System movement;     -   Battery usage.

The data gathered 402 from the sensors may be used for generating both the performance profile and the usage profile.

The method may analyze 405 the profile of the performance with respect to a profile of the usage relating to the types of activity the computer system is used for. The analysis may use weighting functions for different activities.

For example, such weighting functions may recognize that machines that do heavy lifting for software development have a greater weighting towards processor metrics, and users that use presentation software may have a greater weighting towards the portability factors and hard disk drive vibration monitors.

The analysis 405 may assess the performance profile and usage profile components together; for example, if one resource is under performing, then this may be correlated to the usage of another resource, which builds the case for a system upgrade.

The method may determine 406 if the analysis indicates that the performance of the computer system is an inhibitor to productivity of the user for current usage and activities. If so, determine 407 if the computer system is suitable for other activities, for example, as shown by a profile of usage of another computer system. If it is not suitable for other activities, it may be taken out of service 408. If it is suitable for other activities it may be allocated 409 to another user.

If the computer system is not an inhibitor to productivity, it may be maintained 410 in its current role and may be continued to be monitored 401.

Multiple computer systems may be monitored simultaneously within an enterprise. The monitoring method may be carried out remotely via a network connection with each computer system. An overall allocation of computer systems may be optimized within an enterprise by analyzing the monitored data.

In some embodiments, the analysis may include the following aspects compared between performance and usage.

Peak Resource Usage

Peak resource usage is a metric that is derived from looking at a number of factors such as CPU usage and disk latency over a period of time.

If peak resource usage regularly approaches 100% for any individual resource or a mixture of resources for a sustained burst of activity (between 3 and 20 seconds), then this may indicate that a particular application is struggling to perform to the user's expectations given the constraints of the resources it has at its disposal.

If a resource is used consistently highly (for example, CPU usage rarely drops below 60%) then this may be an indicator that the software being used by the user is not suitable for this hardware, and would benefit from more modern equipment.

Software Analysis

If a workstation has known development software installed, then the resource usage of the workstation can be mapped against known profiles for given activities with that software. For example, two developers may have identical copies of the development software installed on their machines, but they may be programming in different projects. In this example, one is working on a large Java (Java is a trademark of Sun Microsystems, Inc.) project with code coverage tools, and the other in Perl (Perl is a trademark of Perl.org). The Java programmer can be expected to drive higher resource utilization due to the relatively high overheads of running the Java virtual machine in order to complete testing, and code coverage profiling. In this case, the Java programmer would have a strong case to have a more powerful machine, and thus a quicker hardware refresh.

Movement Analysis

Hard disk drive accelerometer data can be used to assess how often a laptop is removed from a desk. This can in turn be used to identify that the machine is used while travelling, or on multiple sites. This would imply that the user would benefit from any new technology to improve portability, so could be considered for a quicker refresh if this technology were made available

Power Usage

Battery life data can be used to determine whether a user has to plug his/her laptop into an external power supply more often due to a degraded battery. This can indicate that the user has been forced to change their natural workflow due to a new hardware constraint, and would benefit from a replacement battery or hardware refresh in order to restore lost productivity.

If it is seen that at the end of the computer system lifecycle, the user is not being inhibited by the computer system performance, the life of the machine may be extended. A typical example could be a computer system used by a manager that simply runs email, a web browser and an editor program. These may not have a great system impact, so the current computer system may be sufficient and fit for purpose.

Referring to FIGS. 5A and 5B, graphs 500, 550 show two examples where the computer system is not performing due to resource constraints. The graphs 500, 550 show the resource percentage used 510 against time 520 for a hard disk drive 501, 551, a CPU 502, 552, and temperature 503, 553. In the case of temperature 503, 553, the resource percentage is the temperature rise.

In FIG. 5A, the graph 500 shows a hard disk bound task in which the percentage of usage of the hard disk drive 501 is consistently very high. In FIG. 5B, the graph 550 shows a cooling bound task in which the temperature 553 is too high resulting in the throttling of CPU 551 and hard disk drive 552 to prevent damage to the computer system.

In both cases, the amount of work done by the application in a set amount of time is reduced, which would lead to longer response times and lead to user frustration, in turn leading to loss of productivity.

Example

A laptop has been heavily used, has been used in extreme heat conditions, and has been dropped several times over its lifetime. It has developed several flagged bad sectors on disk, and it occasionally shuts down because of overheating.

A) It is used for heavy graphics rendering for use in a vital real-time service—the described monitoring and analysis indicates that it has likely already come to the end of its useful life. B) It is used for occasional Internet browsing and intermittent access to emails—the described monitoring and analysis indicates that its useful life may continue for some time.

It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

Use of the phrase “at least one of . . . or” should not be construed to be exclusive unless explicitly stated or recited otherwise. For instance, the phrase “X comprises at least one of A, B, or C” does not mean that X comprises only one of {A, B, C}; it does not mean that X comprises only one instance of each of {A, B, C}, even if any one of {A, B, C} is a category or sub-category; and it does not mean that an additional element cannot be added to the non-exclusive set (e.g., X can comprise {A, B. Z}).
